[PATCH 1/2] lib/gpu_cmds: expose num_threads_in_tg parameter for tests

Jan Maslak jan.maslak at intel.com
Mon May 26 00:13:03 UTC 2025


Expose parameter num_threads_in_tg in (gen8|xehp)_fill_interface_descriptor
functions, so that it can be set from the tests.
Also update rest of the code to accommodate this change, passing in
the default value - 1.
